1) Radial injection cylinder feed eliminates direct hydraulic axial loading of the motor casing.
2) Larger cylinder feed channels for reduced power loss with high flows.
3) Stronger castings and internal reinforcement ribbing: increased casing strength and stiffness for higher internal and external load capacity.
4) High load capacity bearings for applications requiring high lifetime, high power/pressure, high external loads.
5) Larger cylinder trunnions for increased strength and stiffness and reduced specific loads.
6) Cylinder trunnions with hydraulic balancing to reduce friction, wearing and heat generation, enabling operation with higher powers and improved efficiency.
7) Compatibility with shafts, adaptors, distributors of the motors of other preceding series.
8) Standardization of components for increased modularity and flexibility as regards interchangeability of displacements, spare parts and options.
9) Reduced number of components for a more simple and reliable design.
10) Compatibility with non-polluting oils.
